Finally picked up a Surface Laptop and installed B44.
No issues at all, runs great and the same great experience I’ve had on the desktop and under Parallels on the MBP.
Still a Mac man for ease of use, but needed the Surface for a particular project so running Scrivener on it is a bonus. One thing I will likely be doing is using the Surface for Scrivener more often while travelling when I might otherwise have used the iPad. The Surface is super light and good keyboard. Trackpad is not Apple territory, but better than most. I did consider the Surface pro 7 but settled for the Laptop with it’s slightly larger screen, and better for use on lap.
